My own solution to this is to store the server key fingerprints in a public Git repository, which can then be pulled from on all devices that need to be able to connect.

This works nicely for my own personal setup with a few servers. It may be possible to scale this to a larger environment with multiple users too.

Then main benefit is that whenever a server is rebuilt (which can be quite regularly when using infra-as-code/infra automation), I don't have to go and manually update every single client that needs to be able to connect.
